Comment (by mdavis):
Yes, that is the repo for OverlayNG.
It would be great if you are able to test this. I'm happy to help with
advice on building and running JTS.
You can use `WKBWriter` to serialize geometry data. (I assume you are
creating the data synthetically, since otherwise you would already have an
image of the data?).
If you are building from source, you could even add some code at the point
the exception is thrown to write out just the geometries which cause the
exception (as opposed to the full union() input dataset). The location is
given in the stack trace.
